[Sending section]
The delivery unit 40 delivers each of the modeling materials 18A to 18C onto the table 16 and applies them thereon. Further, as shown in FIG. 2, the delivery unit 40 adjusts the delivery amount according to the difference in path lengths 56A to 56C that occur between the inner side 52 and the outer side 54 when changing the application direction 50 of each of the modeling materials 18A to 18C. Each of the modeling materials 18A to 18C whose inner side 52 and outer side 54 have been changed is sent out. In other words, the amount of continuous fibers contained in each of the shaping materials 18A to 18C is changed between the inner side 52 and the outer side 54.

Here, changing the coating direction 50 includes, for example, turning back the coating direction 50 or curving the coating direction 50.

As shown in FIG. 1, the delivery section 40 is composed of a tapered nozzle. The upper surface 40A is formed with insertion holes (not shown) into which the respective modeling materials 18A to 18C pulled out from the respective reels 28A to 28C are inserted. Furthermore, as shown in FIG. 3, the lower surface 40B of the delivery section 40 is formed with a discharge port 58 for discharging each of the modeling materials 18A to 18C side by side.

The discharge port 58 is wide in a transverse direction 60 that intersects with the coating direction 50 in which each of the modeling materials 18A to 18C is applied. is formed into a long rectangular shape.

At the discharge port 58, the first modeling material 18A from the first reel 28A is fed out from the left side in the width direction in FIG. 18B is sent out. Further, from the right side of the discharge port 58 in the width direction in FIG. 3, the third shaping material 18C from the third reel 28C is fed out.

The supply amount of each of the modeling materials 18A to 18C per unit time to be supplied to the delivery section 40 is controlled based on the shape data of the object 12 to be modeled, and the continuous fibers contained in each of the modeling materials 18A to 18C are The supply amount per unit time is controlled.

This will be specifically explained using FIG. 2. That is, when changing the application direction 50 of each of the shaping materials 18A to 18C based on shape data and folding them back on a plane, the first path length 56A of the first shaping material 18A located on the outside 54 of the folded portion 62 is changed. is longer than the second path length 56B of the second shaping member 18B located inside it. Further, in the folded portion 62, the second path length 56B of the second shaping material 18B is longer than the third path length 56C of the third shaping material 18C located inside thereof.

Then, the control unit 34 grasps each path length 56A to 56C of each of the modeling materials 18A to 18C based on the shape data before changing the coating direction.

Therefore, the control unit 34 controls the rotation of each pull-out roll 32A to 32C based on the path lengths 56A to 56C of each of the modeling materials 18A to 18C and the coating speed of each of the modeling materials 18A to 18C, which are grasped before changing the coating direction. Control speed.

For example, the rotational speed of the first drawer roll 32A is made faster than the second drawer roll 32B, and the rotational speed of the second drawer roll 32B is made faster than the rotational speed of the third drawer roll 32C.

As a result, the amount of supply of each of the modeling materials 18A to 18C per unit time is adjusted according to the difference between the path lengths 56A to 56C that occur between the inside 52 and the outside 54 in the folded portion 62, and the amount of each of the modeling materials 18A to 18C is The delivery amount of the included continuous fibers is changed between the inner side 52 and the outer side 54.

[Angle change roll]
As shown in FIG. 1, the angle changing roll 42 is set so that the angle α formed by each of the shaping materials 18A to 18C, which is supplied from the delivery section 40 to the pressure roller 44, with respect to the shaping surface 14 is an acute angle. , the angle α is set to be 15 degrees or more and 45 degrees or less.

[Heating section]
The first heating section 46 heats each of the forming materials 18A to 18C from the upper UH side between the angle changing roll 42 and the pressure roller 44, and heats each of the forming materials 18A to 18C located on the side opposite to the forming surface 14. heats the surrounding area. The second heating unit 48 heats each of the forming materials 18A to 18C from the side between the angle changing roll 42 and the pressure roller 44, and heats the respective forming materials 18A to 18C located on the forming surface 14 side. Heat the area on the surface.

As a result, each of the forming materials 18A to 18C is heated from both sides in the stacking direction, and bonding of adjacent forming materials 18A to 18C is promoted.

Examples of the first heating section 46 and the second heating section 48 include heating means for heating each of the shaping materials 18A to 18C. Examples of this heating means include a hot air supply device that heats each of the modeling materials 18A to 18C by applying hot air to each of the modeling materials 18A to 18C, a laser device that heats each of the modeling materials 18A to 18C by irradiating a laser beam to each of the modeling materials 18A to 18C, and a An example is a heater that heats by adding radiant heat to ~18C. An example of the heater is a halogen heater.

[Pressure roller]
The pressure roller 44 is formed in a cylindrical shape, and presses and crushes each of the molding materials 18A to 18C, in which the resin has been melted by the respective heating sections 46 and 48, toward the table 16. As a result, each of the shaping materials 18A to 18C is flattened and fixed by being sandwiched between them and the shaping surface 14. In addition, at the locations where the modeling materials 18A to 18C are stacked, the upper and lower modeling materials 18A to 18C are strongly bonded to each other.

Thereby, each of the modeling materials 18A to 18C supplied from the supply amount control section 24 is supplied onto the table 16, and the object 12 is modeled based on the modeling data.

(action/effect)
The operation of this embodiment with the above configuration will be explained.

When changing the application direction 50 of each of the shaping materials 18A to 18C, the amount of continuous fiber delivered is changed between the inner side 52 and the outer side 54 according to the difference in path length 56A to 56C that occurs between the inner side 52 and the outer side 54. .

As a result, even if each of the shaping materials 18A to 18C having continuous fibers is used, wrinkles may be formed in the third shaping material 18C disposed on the inner side 52, or wrinkles may be formed in the continuous fibers of the first shaping material 18A disposed on the outer side 54. The occurrence of cuts is suppressed.

Therefore, when changing the application direction of the shaping material, it is possible to suppress a decrease in the strength of the shaping material, compared to a case where the amount of continuous fibers delivered is constant in the width direction of the shaping material.

Moreover, since the difference in path length that may occur when changing the coating direction is reduced, the productivity of the product can be increased compared to the case where a thin shaping material is used.

Further, the discharge port 58 of the delivery section 40 is wide in a transverse direction 60 that intersects with the coating direction 50.

Therefore, compared to the case where the discharge port 58 is narrow, it contributes to improving the productivity of products .

<Second embodiment>
FIG. 4 is a diagram showing a modeling apparatus 10 according to the second embodiment, in which the same or equivalent parts as in the first embodiment are given the same reference numerals and explanations are omitted, and only different parts will be explained.

The modeling apparatus 10 of this embodiment differs from the first embodiment in the discharge port formed in the delivery section 40.

[Sending section]
A plurality of discharge ports for discharging each of the modeling materials 18A to 18C are formed on the lower surface 40B of the delivery section 40, and the discharge ports are arranged in parallel in a cross direction 60 intersecting the application direction 50. It is configured to include a first discharge port 70 and a second discharge port 72.

Further, on the lower surface 40B of the delivery section 40, there is another row of discharge ports 74 that discharges the second modeling material 18B from a position shifted in the coating direction 50 from the row of discharge ports 70 and 72 arranged in the intersecting direction 60. It is formed. Further, the separate row of discharge ports 74 is arranged in a region 76 that passes between the adjacent first discharge ports 70 and second discharge ports 72 and extends in the coating direction 50 .

Although the separate row discharge ports 74 are arranged on the upstream side in the coating direction 50 as an example, the present invention is not limited thereto, and they may be arranged on the downstream side in the coating direction 50. Further, a plurality of separate rows of discharge ports 74 may be provided.

(action/effect)
In this embodiment, the same or equivalent parts as in the first embodiment can provide the same effects as in the first embodiment.

Furthermore, since the delivery unit 40 has a plurality of discharge ports 70 to 74, the amount of each modeling material 18A to 18C delivered from each discharge port 70 to 74 can be adjusted as compared to a case where there is a single discharge port. It becomes easier to adjust the amount of continuous fiber delivered.

Further, the separate row of discharge ports 74 of the delivery section 40 is arranged in a region 76 that passes between the adjacent first discharge port 70 and second discharge port 72 and extends in the coating direction 50 .

Therefore, compared to the case where the separate row of discharge ports 74 is not provided and only one row of discharge ports is provided, the arrangement density of the forming materials 18A to 18C containing continuous fibers is increased.

Further, the modeling material supply section 80 includes an impregnating section 90 that impregnates each of the continuous fibers 82A to 82C with resin 88 to form each of the modeling materials 18A to 18C.

(continuous fiber)
Each of the continuous fibers 82A to 82C is composed of a plurality of wire rods. The wire rods of each of the continuous fibers 82A to 82C are made of carbon fiber, for example, and compared to the case of using a modeling material in which continuous fibers are impregnated with resin, the reel to be wound can be made smaller in diameter and more compact. The goal is to

In this embodiment, a case will be described in which the wire rods of the continuous fibers 82A to 82C are made of carbon fiber, but the wire rods are not limited to this, and may be made of glass fiber. A single continuous fiber F (the symbol given when indicating a single continuous fiber is "F") constituting each of the continuous fibers 82A to 82C has a diameter of 5 μm to 30 μm. Hundreds to tens of thousands of pieces are pulled out from each reel 84A to 84C.

(Impregnated part)
The impregnation section 90 includes a resin supply section 92 filled with resin 88 and a cylindrical casing 94 to which the resin 88 is supplied from the resin supply section 92 . The resin 88 supplied from the resin supply section 92 may be a thermoplastic resin. This resin 88 is made of molten PP (polypropylene), for example, and the melting point of PP is about 160°C.

Note that in this embodiment, a case will be described in which PP is used as the resin 88, but the resin 88 is not limited to this. For example, resin can be used as PA (polyamide (nylon)), PPS (polystyrene), PC (polycarbonate), PEEK (polyetheretherketone), PEI (polyetherimide), PA6 (polyamide 6 (6 nylon)), PA11 ( It may also be composed of polyamide 11).

Continuous fibers 82A to 82C are inserted from the upper surface 94A of the casing 94, and when the plurality of continuous fibers F pass through the casing 94, the resin 88 is impregnated between the continuous fibers F to form a linear shape. The modeling material is molded. Each of the shaped materials 18A to 18C thus formed can be described as a fiber-reinforced resin in which the resin is reinforced with continuous fibers.

As shown in FIG. 6, the lower surface 94B of the casing 94 has a first delivery hole 96 corresponding to the first delivery port 70 of the delivery unit 40 and a second delivery hole corresponding to the second delivery port 72 of the delivery unit 40. 98, and a third delivery hole 100 corresponding to the separate row outlet 74 of the delivery section 40 are formed. Furthermore, each of the delivery holes 96 to 100 is formed in a rectangular shape.

A second shutter 104 is slidably provided. Further, the third delivery hole 100 is slidably provided with a third shutter 106 that changes the opening width of the third delivery hole 100.

Each of the shutters 102 to 106 is configured to open and close in response to a signal from the control unit 34, and the control unit 34 opens each of the delivery holes 96 to 100 by operating each of the shutters 102 to 106. Adjust width.

Thereby, when changing the application direction 50 of each of the modeling materials 18A to 18C based on the shape data of the object 12, the control unit 34 controls the third object placed on the inner side 52, for example, as shown in FIG. The material 18C is made thinner than the first shaping material 18A arranged on the outside 54.

At this time, the amount of resin 88 impregnated into each of the continuous fibers 82A to 82C is approximately the same. Therefore, when changing the application direction 50, the content of the resin 88 in the third shaping material 18C disposed on the inner side 52 is greater than the content of resin 88 in the first shaping material 18A disposed on the outer side 54.

In other words, the third shaping material 18C disposed on the inside 52 has a low density of continuous fibers (sparse), and the first shaping material 18A disposed on the outside 54 has a high density of continuous fibers (dense).

The respective modeling materials 18A to 18C sent out from the respective delivery holes 96 to 100 are pulled out from the impregnating section 90 by the respective drawing rolls 32A to 32C of the supply amount control section 24, and are also drawn out from the corresponding discharge ports 70 to 70 of the delivery section 40. It is discharged from. That is, when changing the application direction 50, the delivery unit 40 replaces the third shaping material 18C from the second discharge port 72 located on the inside 52 with the first modeling material 18A from the first discharge port 70 located on the outside 54. Make it thinner.

As a result, the third width dimension 114 of the third shaping member 18C disposed on the inner side 52 of the folded portion 62 becomes narrower than the second width dimension 112 of the second shaping member 18B disposed on the outer side 54 thereof. Further, the second width dimension 112 of the second shaping material 18B is narrower than the first width dimension 110 of the first shaping material 18A disposed on the outside 54 thereof.

Further, when changing the application direction 50, the delivery unit 40 adjusts the content of the resin 88 of the third modeling material 18C from the second discharge port 72 located on the inside 52 to the first discharge port 72 located on the outside 54. The content of resin 88 is set to be larger than that of the first modeling material 18A from .

(action/effect)
In this embodiment, the same or equivalent parts as in the first and second embodiments can provide the same effects as in the first and second embodiments.

Moreover, compared to the case where the thickness of the shaping material is uniform in the width direction, it is possible to suppress the swelling of the third shaping material 18C arranged on the inner side 52 of the folded part 62, which is the corner part.

Furthermore, by adjusting the content of resin 88 in each of the shaping materials 18A to 18C, it is possible to adjust the ratio of continuous fibers contained in each of the shaping materials 18A to 18C.

That is, the impregnation section of the modeling material supply section 80 includes a first impregnation section 120 that impregnates the first continuous fiber 82A with the resin 88 to form the first modeling material 18A, and a first impregnation section 120 that impregnates the second continuous fiber 82B with the resin 88. and a second impregnated part 122 that forms the second shaped material 18B. Further, the impregnation section of the modeling material supply section 80 includes a third impregnation section 124 that impregnates the third continuous fiber 82C with the resin 88 to form the third modeling material 18C.

Each of the impregnating parts 120 to 124 is configured so that the opening width of an outlet (not shown) formed on the lower surface can be changed and the proportion of the resin 88 can be changed. When changing the application direction 50 of each of the modeling materials 18A to 18C based on the shape data of the modeled object 12, the control unit 34 connected to each of the impregnating parts 120 to 124 controls, for example, a third model disposed on the inner side 52. The material 18C is formed to be thinner than the first shaping material 18A disposed on the outside 54.

As a result, as shown in FIG. 7, the third width dimension 114 of the third shaping member 18C disposed on the inner side 52 of the folded portion 62 is the second width of the second shaping member 18B disposed on the outer side 54 thereof. It is narrower than dimension 112. Further, the second width dimension 112 of the second shaping material 18B is narrower than the first width dimension 110 of the first shaping material 18A disposed on the outside 54 thereof.

<Fifth embodiment>
FIGS. 9 to 11 are diagrams showing a modeling apparatus 10 according to a fifth embodiment, and parts that are the same or equivalent to those in the third embodiment are given the same reference numerals and explanations are omitted, and only different parts are omitted. explain.

The modeling apparatus 10 of this embodiment differs from the third embodiment in the configuration of the modeling material supply section.

(Building material supply department)
As shown in FIG. 9, this modeling material supply section 130 is inserted between each of the continuous fibers 82A to 82C pulled out from each reel 84A to 84C, and divides the collected continuous fibers F into small parts. A plate 132 is provided. Each dividing plate 132 is driven by a drive section (not shown).

Each drive unit is connected to a control unit 34, and the control unit 34 controls the insertion of each dividing plate 132 into the continuous fiber F and the insertion position in the width direction based on the shape data of the modeled object 12. do. As a result, each of the continuous fibers 82A to 82C is supplied to the impregnating section 90 in the number divided by the dividing plate 132, and the resin 88 is impregnated in the impregnating section 90 to form each of the shaping materials 18A to 18C.

Specifically, when changing the application direction 50 of each of the shaping materials 18A to 18C based on the shape data, the control unit 34 changes the number of continuous fibers F forming the third shaping material 18C disposed on the inner side 52 to the outer side 54, for example. The number is smaller than the number of continuous fibers F forming the first shaping material 18A to be arranged.

Each of the modeling materials 18A to 18C formed in the impregnation section 90 is sent to the delivery section 40, and is discharged from the discharge port 58 of the delivery section 40, as shown in FIG.

As a result, as shown in FIG. 11, for example, the delivery unit 40 changes the number of continuous fibers F of the third shaping material 18C from the discharge port 58 located on the inside 52 to the discharge port 58 located on the outside 54 when changing the coating direction. The number is smaller than the number of continuous fibers F of the first shaping material 18A from the outlet 58.

Furthermore, each of the modeling materials 18A to 18C is impregnated with approximately the same amount of resin 88. Therefore, when changing the application direction 50, the delivery unit 40 changes the ratio of continuous fibers included in the third forming material 18C from the discharge port 58 located on the inside 52 to the ratio of continuous fibers contained in the third forming material 18C from the discharge port 58 located on the outside 54. The ratio of continuous fibers contained in the first shaping material 18A is made smaller than that of the first shaping material 18A.

Note that when changing the application direction 50 of each of the modeling materials 18A to 18C, the delivery amount of each of the continuous fibers 82A to 82C can be changed between the inner side 52 and the outer side 54 depending on the difference in path length between the inner side 52 and the outer side 54. The impregnating section 90 may have a built-in conveyance speed adjusting device with a buffering function for changing and sending out.

(action/effect)
This embodiment can also provide the same effects as the third embodiment.

When changing the application direction 50, the delivery unit 40 also adjusts the number of continuous fibers F of the third shaping material 18C delivered from the discharge port 58 located on the inside 52 to the number of continuous fibers F delivered from the discharge port 58 located on the outside 54, for example. The number of continuous fibers S of the first shaping material 18A sent out from the part 58 is reduced.

For this reason, compared to the case where the number of continuous fibers F is equal in the width direction of the shaping material, it is possible to make the number of continuous fibers S arranged in the folded portion 62, which is the corner portion, equal.

Further, when changing the application direction 50, the delivery unit 40 changes the ratio of the continuous fibers F included in the third forming material 18C from the discharge port 58 located on the inside 52 to the ratio of the continuous fibers F included in the third forming material 18C from the discharge port 58 located on the outside 54. The ratio of continuous fibers F contained in the first shaping material 18A is set to be smaller than that of the continuous fibers F contained in the first shaping material 18A.

Therefore, compared to a case where the ratio of continuous fibers F included in each of the shaping materials 18A to 18C is equal in the width direction, it is possible to make the continuous fibers F arranged in the folded portions 62, which are corner portions, equal. becomes.

(comparative test)
FIG. 12 is a diagram showing comparison results between each example and a comparative example.

The width dimension of the modeling material to be applied is 4 mm, the thickness dimension is 0.5 mm, and the modeling material with a continuous fiber ratio Vf of 50% in the standard modeling material is turned 180 degrees and the appearance quality at the folded part is evaluated. did.

In Example 1, modeling is performed using a plurality of modeling materials, the modeling materials wound around a reel are used, and an impregnating section for impregnating continuous fibers with resin is not provided. Further, the thickness and Vf of the modeling material are not changed between the inside and outside of the folded portion.

In Example 2, a plurality of shaping materials are used for modeling, the continuous fibers wound around a reel are carbon fibers, and an impregnated portion is provided. Further, the thickness and Vf of the shaping material are not changed between the inside and outside of the folded portion.

In Example 3, a plurality of shaping materials are used for modeling, the continuous fibers wound around a reel are carbon fibers, and an impregnated portion is provided. Further, in the folded portion, the thickness of the inner modeling material is made thinner, but Vf is not changed.

In Example 4, a plurality of shaping materials are used for modeling, the continuous fibers wound around a reel are carbon fibers, and an impregnated portion is provided. Further, in the folded part, the thickness of the modeling material is not changed between the inside and outside, but Vf is increased on the outside.

In the comparative example, modeling is performed using a single modeling material, and the modeling material wound around a reel is used. Also, it does not have an impregnating section.

The test results show that in the comparative example, wrinkles and cuts occurred at the folded portion, but in each of the examples, no wrinkles or cuts were found, and the appearance quality was high.

In the embodiment described above, the thickness and Vf (ratio of continuous fibers F included in the shaping material 18) of the first shaping material 18A disposed on the outside in the folded part 62 and the third shaping material 18C disposed on the outside are different. Although a case has been described in which the value is changed, the present invention is not limited to this.

<Sixth embodiment>
FIG. 13 is a diagram showing a shaping material 18 according to the sixth embodiment. In this shaping member 18, the thickness of the fourth shaping member 18D and the seventh shaping member 18G disposed on the outside is thinner than the thickness of the fifth shaping member 18E and the sixth shaping member 18F disposed on the inside.

(action/effect)

In this embodiment, even when bending to either the side where the fourth shaping member 18D is arranged or the side where the seventh shaping member 18G is arranged, it is easier to bend the inner side where the curvature is higher. It becomes possible to do so.

This facilitates bending toward the side where the fourth shaping member 18D is arranged and the side where the seventh shaping member 18G is arranged, making it possible to facilitate curved modeling.

<Seventh embodiment>
FIG. 14 is a diagram showing a modeling material 18 according to the seventh embodiment. In this modeling material 18, the Vf (ratio of continuous fibers F included in the modeling material 18) of the fourth modeling material 18D and the seventh modeling material 18G arranged on the outside is the same as that of the fifth modeling material 18E and the seventh modeling material 18G arranged on the inside. It is lower than the sixth shaping material 18F.

(action/effect)

In this embodiment, even when bending to either the side where the fourth shaping member 18D is arranged or the side where the seventh shaping member 18G is arranged, it is easier to bend the inner side where the curvature is higher. It becomes possible to do so.

This facilitates bending toward the side where the fourth shaping member 18D is arranged and the side where the seventh shaping member 18G is arranged, making it possible to facilitate curved modeling.

In addition, in the seventh embodiment, the Vf (the proportion of continuous fibers F included in the shaping material 18) of the fourth shaping material 18D and the seventh shaping material 18G arranged on the outside is compared with that of the fifth shaping material disposed on the inside. Although it is lower than 18E and the sixth shaping material 18F, it is not limited to this.

For example, in the case of using a single shaping material, Vf (the proportion of continuous fibers F included in the shaping material 18) may be continuously changed so that it decreases from the inside toward the outside.

<Example>
15 to 18 are diagrams showing Examples, and FIGS. 15 and 16 show Example 5 to Example 23 and a comparative example.

(Common subject matter)
In each Example and Comparative Example, each shaping material was bent in a 90° direction while drawing a circular arc with a radius of 5 mm to form a curved line and evaluated. As evaluation items, evaluation was performed based on electrical resistance value (ΔR/ΔR1) and evaluation of bending elastic modulus.

The electrical resistance value was expressed as electrical resistance value=(ΔR/ΔR1), where R1 is the resistance value of the straight part of the modeling material, R2 is the resistance value of the curved part, and ΔR=(R2−R1).

To measure the resistance value R1 of the straight part of the building material, as shown in FIG. This is done by measuring the voltage at the location with a voltmeter 204. Then, a resistance value R1 is determined from the voltage value measured by the voltmeter 204, the current value measured by the ammeter 202, and the specified distance K1.

To measure the resistance value R2 of the curved portion of the shaped material 18, as shown in FIG. The voltage between the starting point 210A and the ending point 210B of the curved portion 210 is measured using the voltmeter 204. It is assumed that the starting point 210A and the ending point 210B of the curved portion 210 are separated by a prescribed distance K2.

Then, a resistance value R2 is determined from the voltage value measured by the voltmeter 204, the current value measured by the ammeter 202, and the specified distance K2.

Although FIG. 18 shows a state in which the modeling material 18 has made a U-turn, the resistance value R2 is measured at a location corresponding to the curved portion 210 of the embodiment.

In the evaluation of the electrical resistance value (ΔR/ΔR1), it is determined that the evaluation criteria are satisfied when (ΔR/ΔR1)≦1. Furthermore, in the evaluation of the bending elastic modulus, when the bending elastic modulus≧20Pa, it is determined that the evaluation criteria are satisfied. When the evaluation of the electrical resistance value (ΔR/ΔR1) and the evaluation of the bending elastic modulus are satisfied, the judgment result is determined to be good and is indicated by a circle.

(Example 5)
In Example 5, a standard modeling material is used. The continuous fibers of this modeling material were Torayca (registered trademark: hereinafter the same) T300 manufactured by Toray Industries, Inc., and the elongation rate of the continuous fibers was 1.5%. This continuous fiber is used without being cut and is not twisted.

The Vf (ratio of continuous fibers contained in the modeling material: the same applies hereinafter) of the modeling material was 50%, and the content of the compatibilizer for kneading the resin and continuous fibers of the modeling material was 6%. The temperature of the modeling material supplied to the pressure roller of the modeling device is 250° C., and the modeling material is delivered onto the table.

(Comparative example)
In the comparative example, the continuous fiber of the modeling material was Torayca T300 manufactured by Toray Industries, Inc., and the elongation rate of the continuous fiber was 1.5%. This continuous fiber is used without being cut and is not twisted. The Vf of the modeling material was 50%, and the content of the compatibilizer was 6%. The temperature of the modeling material supplied to the pressure roller of the modeling device is 250° C., and the modeling material is delivered onto the table.

(Differences between each example and comparative example)
In each embodiment, the shaping material changes the delivery amount of continuous fibers in accordance with the difference in path length between the inside and outside when changing the application direction.

On the other hand, in the comparative example, the amount of continuous fiber delivered is not changed in response to the difference in path length between the inside and outside when changing the coating direction.

In each example, modeling was performed by arranging four modeling materials having a width of 1 mm and a thickness of 0.5 mm in parallel. As a method, for example, four discharge ports are provided in the delivery section 40 of the second embodiment to form four modeling materials.

On the other hand, in the comparative example, modeling was performed using one modeling material having a width of 4 mm and a thickness of 0.5 mm.

(Example 6, Example 12, Example 18)
Examples 6, 12, and 18 are different from other examples and comparative examples in the elongation rate of the continuous fibers used.

In Example 6, the continuous fibers of all the modeling materials were Torayca T1000GB manufactured by Toray Industries, Inc., and the elongation rate of the continuous fibers was 2.2%.

In Example 12, in the curved part, only the continuous fibers of the modeling material placed inside were Torayca T1000GB manufactured by Toray Industries, Ltd., and the elongation rate was set to 2.2%, and the continuous fibers of the other modeling materials were manufactured by Toray Industries, Inc. The trading card T300 manufactured by the company was used, and the elongation rate was set to 1.5%.

That is, the elongation rate of the continuous fibers of the modeling material discharged from each discharge port of the delivery section is changed by each discharge port arranged in the cross direction. As a result, a shaped material is formed in which the continuous fibers have different elongation rates in the cross direction.

In Example 18, the continuous fibers of the outermost of the four shaping materials arranged in parallel were Torayca T1000GB manufactured by Toray Industries, Inc., and the elongation rate of the continuous fibers was 2.2%. As a result, the elongation rate of the continuous fibers of the shaping material placed inside the curved portion is set to 2.2%.

In other words, by changing the elongation rate of the continuous fibers of the modeling material discharged from each discharge port of the delivery section at each discharge port arranged in the cross direction, it is possible to create a molding material with a different elongation rate of the continuous fibers in the cross direction. It is formed.

Note that the other conditions are the same as in Example 5.

(Example 7, Example 13, Example 19)
In Example 7, Example 13, and Example 19, the Vf of the modeling material used was different compared to other Examples and Comparative Examples, and Vf was changed by increasing the amount of resin in the modeling material. ing.

In Example 7, the Vf of all the modeling materials was small compared to the others, and the Vf was set to 20%.

In Example 13, in the curved portion, only the Vf of the shaping material placed inside was set to 20%, and the Vf of the other shaping materials was set to 50%.

In Example 19, among the four shaping members arranged in parallel, the outermost shaping member had a Vf of 20%, and the other shaping members had a Vf of 50%. Thereby, when modeling the curved part, the Vf of the modeling material placed inside the curved part is set to 20%.

Note that the other conditions are the same as in Example 5.

(Example 8, Example 14, Example 20)
In Examples 8, 14, and 20, compared to other Examples and Comparative Examples, the shaping material includes cut fibers obtained by cutting continuous fibers. The cut fibers are obtained by cutting the aforementioned continuous fibers, and the length dimension of the cut fibers is 0.1 mm or more and 3 mm or less. Further, the Vf of the modeling material using cut fibers is 30%.

In Example 8, in comparison with the others, cut fibers obtained by cutting continuous fibers are used in all the modeling materials.

In Example 14, in the curved portion, cut fibers are used only for the shaping material placed inside, and uncut continuous fibers are used for the other shaping materials.

That is, the modeling material is formed by discharging a modeling material having continuous fibers and a modeling material having cut fibers from different discharge ports arranged in a cross direction. Thereby, the region having continuous fibers and the region having cut fibers are arranged side by side in the cross direction of the modeling material.

In Example 20, cut fibers are used for the outermost of the four shaping materials arranged in parallel, and continuous fibers that are not cut are used for the other shaping materials. Thereby, when modeling the curved portion, a modeling material using cut fibers is placed inside the curved portion.

Moreover, a shaping material is formed by discharging a shaping material having continuous fibers and a shaping material having cut fibers from different discharge ports arranged in a cross direction. Thereby, the region having continuous fibers and the region having cut fibers are arranged side by side in the cross direction of the modeling material.

Note that the other conditions are the same as in Example 5.

(Example 9, Example 15, Example 21)
In Examples 9, 15, and 21, the content of the compatibilizer contained in the resin of the modeling material is smaller than in the other Examples and Comparative Examples. Note that the content of the compatibilizer may be set to zero. This reduces the adhesiveness between the continuous fibers and the resin. In other words, the modeling material uses a resin that has low adhesiveness to continuous fibers.

In Example 9, the content of the compatibilizer contained in the resin of the modeling material was set to 2% in all the modeling materials compared to the others, and the content of the compatibilizer contained in the resin of the other modeling materials was set to 2%. The amount was set to 6%.

In Example 15, in the curved part, the content of the compatibilizer contained in the resin of only the modeling material placed on the inside was set to 2%, and the content of the compatibilizer contained in the resin of the other modeling materials was 2%. The content was set to 6%.

In Example 21, the content of the compatibilizer contained in the resin of the outermost of the four shaping members arranged in parallel was 2%. Thereby, when modeling the curved part, the modeling material containing 2% of the compatibilizer contained in the resin is placed inside the curved part.

Note that the other conditions are the same as in Example 5.

(Example 10, Example 16, Example 22)
In Example 10, Example 16, and Example 22, the shaping material includes twisted continuous fibers, compared to other examples and comparative examples.

In Example 10, compared to the others, twisted continuous fibers are used in all the shaping materials. The twist rate of the continuous fibers is, for example, 45 degrees, and each continuous fiber is twisted so as to be inclined at 45 degrees with respect to the longitudinal direction of the continuous fibers.

In Example 16, in the curved portion, twisted continuous fibers are used only in the shaping material disposed on the inside, and the continuous fibers in the other shaping materials are not twisted.

As a result, the twist rate of the continuous fibers arranged in the cross direction of the modeling material is different in the cross direction, and the twist rate of the continuous fibers of the modeling material discharged from each discharge port of the delivery section is changed in the cross direction. A modeling material is formed by setting different discharge ports for each disposed outlet.

In Example 22, twisted continuous fibers are used in the outermost of the four shaping materials arranged in parallel, and the continuous fibers in the other shaping materials are not twisted. Thereby, when modeling the curved part, the modeling material having twisted continuous fibers is placed inside the curved part.

Note that the other conditions are the same as in Example 5.

(Example 11, Example 17, Example 23)
Examples 11, 17, and 23 differ in the temperature of the modeling material delivered onto the table compared to other examples and comparative examples.

In Example 11, compared to the others, the temperature of all the modeling materials delivered onto the table is 280°C.

In Example 17, in the curved portion, only the shaping material disposed on the inside has a temperature of 280°C, and the temperature of the other shaping materials has a temperature of 250°C.

As a result, the temperature of the modeling material sent to the table differs depending on the modeling materials arranged in the cross direction. For example, by setting the temperature of the modeling material sent to each discharge port of the delivery section to be different, it is possible to The temperature of the discharged modeling material is different.

One example of this method is a configuration that includes heating means that heats the modeling materials sent to each discharge port of the delivery section at different temperatures.

In Example 23, the temperature of the outermost of the four shaping members arranged in parallel is 280°C, and the temperature of the other shaping members is 250°C. Thereby, when modeling the curved portion, the modeling material heated to 280° C. is placed inside the curved portion.

Note that the other conditions are the same as in Example 5.

In all of these examples, a value of 1 or less is obtained in the evaluation of the electrical resistance value, and a value of 20 Pa or more is obtained in the evaluation of the flexural modulus, which is obtained from the evaluation of the electrical resistance value and the evaluation of the flexural modulus. All judgment results were good.

In addition, in Examples 6, 12, and 18 in which the elongation rate of the continuous fibers used in the modeling material was changed, the elongation rate on the inside of the curved part was It becomes possible to increase the elongation rate. This makes it possible to easily bend the inner side where the curvature is higher.

Furthermore, in Examples 10, 16, and 22, in which the continuous fibers used in the modeling material were twisted, the twist rate of the continuous fibers was more constant on the inside of the curved portion than when the twist rate was constant in the cross direction. It becomes possible to increase the torsion rate of. This makes it possible to easily bend the inner side where the curvature is higher.

In addition, in Examples 8, 14, and 20 in which cut fibers are used in the modeling material, it is possible to arrange the cut fibers inside the curved portions, compared to the case where continuous fibers are used throughout the cross direction. becomes. This makes it possible to easily bend the inner side where the curvature is higher.

Furthermore, in Examples 11, 17, and 23, where the temperature of the modeling material delivered onto the table differs in the cross direction, the temperature on the inside of the curved part is It becomes possible to increase the temperature. This makes it possible to easily bend the inner side where the curvature is higher.

In addition, in the modeling materials of each example, continuous fibers with different elongation rates were used, twisted continuous fibers were used, cut fibers were used, and the temperature was varied, but the present invention is not limited to these. It's not something you can do. The effects of the present application can be obtained by changing the amount of continuous fiber delivered between the inside and outside in accordance with the difference in path length that occurs between the inside and outside when changing the application direction of the modeling material.

Further, in each embodiment, the case where four modeling materials are arranged in parallel to be modeled has been described as an example, but the present invention is not limited to this.

For example, as shown in FIGS. 3 and 10, in a modeling device that forms a single modeling material using a delivery section 40 equipped with a single discharge port 58, the elongation rate of continuous fibers differs in the cross direction. A shaping material may be used, or a shaping material in which the twist rate of continuous fibers differs in the cross direction may be used. In addition, in a modeling device that forms a single modeling material, it is possible to use a modeling material in which regions having continuous fibers and regions having cut fibers are arranged side by side in the cross direction, or to use a molding material that has different temperatures in the cross direction. You may also use it.
